Palmachim (פלמחים) is a kibbutz in central Israel. Located about ten kilometers south of the Tel Aviv area among the sand dunes of the Mediterranean Sea coast, it falls under the jurisdiction of Gan Raveh Regional Council. In 2004 it had a population of 500.
In 2006 former residents of Elei Sinai, an Israeli settlement in the Gaza Strip evicted during the disengagement plan protested to the government until they were allowed to move to the kibbutz.
The nearby Palmachim Air Force Base houses rocket testing grounds and space launching facilities for the Israel Defense Forces and the Israeli Space Agency, and the Soreq Nuclear Research Center, which houses a small (5MW) nuclear research reactor, take advantage of the area's relative isolation. There is also a desalinization plant nearby.
There are also plans to build a 350-apartment holiday resort on the Palmachim beach, though this has led to several protests.
